67 * "Reg test" tasks - These fill the registers with known values, then check
\r
68 * that each register maintains its expected value for the lifetime of the
\r
69 * task. Each task uses a different set of values. The reg test tasks execute
\r
70 * with a very low priority, so get preempted very frequently. A register
\r
71 * containing an unexpected value is indicative of an error in the context
\r
72 * switching mechanism.
